A member asked:
I hv strted iron suplment three days bck..n my stools are black..what does that mean?
A doctor has provided 1 answer
It's normal: Having black stools and/or constipation is a completely normal, typical side effect from iron supplements. So i wouldn't worry. If you start noticing that the black stools become more tarry in appearance, then i would be worried about gastrointestinal bleeding.
